Question 1 · Hard
A 3-month-old is brought with irritability, vomiting and a bulging fontanelle. He has no fever. The eye examination shows retinal haemorrhages, a CT scan shows subdural haematomas, and X-rays show healing posterior rib fractures. The most likely cause is:
- AA fall from a low bed
- BCongenital hydrocephalus
- CBacterial meningitis
- DAbusive head trauma (shaken baby)
Show answerHide answer
Answer: D · Abusive head trauma (shaken baby)
Subdural haematomas and retinal haemorrhages without a matching history in a young infant are typical of abusive head trauma, caused by violent shaking. Posterior rib fractures occur when the chest is squeezed hard, and healing fractures show earlier injury. The nurse documents findings exactly, keeps the infant safe and follows the hospital's child-protection reporting procedure. The history given by carers often does not match the injuries.
- A: A short fall rarely causes subdural haematoma with retinal haemorrhage and never posterior rib fractures.
- B: Hydrocephalus develops slowly and does not cause retinal haemorrhages or fractures.
- C: Meningitis usually causes fever and does not explain rib fractures.
